6. Testing ALPHA Plus Meter Technical Manual
6-6 TM42-2182D 2003.February.27
Potential indicator and meter engine warnings will be automatically
cleared when the condition causing the warning has been corrected. A
PQM warning will only be cleared once all of the PQM tests pass. The
low battery warning will be cleared when the battery has been
replaced and the meter has performed a self test.
The reverse energy flow warning and demand overload warning will
only be cleared by a demand reset or optical communication with
Elster Electricity meter support software which resets statuses.
F 000000: No warning
This warning code is only displayed when the warning code display
quantity has been programmed into the normal or alternate mode
display sequence with Elster Electricity meter support software. This
indicates that no warning condition exists.
F 000001: Battery warning
This warning code indicates a low battery voltage or missing battery.
ALPHA Plus meters having TOU functionality require a battery to
maintain time and data over an extended power outage.
For TOU configurations, the meter should be de-energized and the
battery should be replaced. Once the new battery has been installed, a
demand reset or communication via Elster Electricity meter support
software will clear the warning code.
Note: Since a battery is not required for demand only ALPHA Plus
meters, this warning can be ignored. It may also be
disabled through Elster Electricity meter support software.
